Subject: mm: migrate: remove unused argument vma from migrate_misplaced_folio()
Date: Tue, 26 Nov 2024 09:56:54 -0600
Commit ee86814b0562 ("mm/migrate: move NUMA hinting fault folio isolation
+ checks under PTL") removed the code that had used the vma argument in
migrate_misplaced_folio.
Since the vma argument was no longer used in migrate_misplaced_folio, this
patch removes it.
